[NTG-context] Leopard and ConTeXt

Hi MacUsers out there, until yesterday I worked with 10.4 and a recent context: no problem (only mkII). Today I finally set up a new machine with 10.5. and MacTeX, run ctxtools --updatecontext. Running a context-file now gives me the right context-version but ends up with: "TeX capacity exceeded, sorry [save size=5000]" Well, I remember this was something about texmf.cnf (or context.cnf?). So I changed the value to 10000, remade the format but still the echo mentions 5000. Some known problem with Leopard and ConTeXt? Maybe PATH stuff? =o( Please help!!! Steffen
